Re: Mk2 Lever frame musings

I have only made the Mk1 version and rolled the top plate on a cutting mat using a bar which was about 1/2" in diameter. I find the cutting mat has just enough 'give' in it to allow a bend (for any model) to be made gently, little by little. I rolled the top of the plate to shape, with a bit mo...

Re: Yard crane gears

If you enlarge the picture, you can see a small gear on the same shaft as the handle. This meshes with the teeth on the large gearwheel. It looks as though you might have to turn the handle as many as 10 or 12 times to make the large gear turn once.

Fret saw blades

Can someone advise me on a suitable fret saw blades? I have never used a fret saw and I am completely unfamiliar with what sort of blade might be used for what purpose.

Re: Solvents

Thank you, all. Some interesting posts.

I have done this and it is quite successful. I don't ...

Solvents

I am curious to know what modellers find to be useful solvents (apart from water) and any particular uses they put them to. I use three: IPA, white spirit and surgical spirit. I use the IPA for degreasing and cleaning sticky bits, white spirit for thinning enamels and cleaning sticky stuff the IPA d...

Re: D&S 04 Siphon help

The cast J hangers are rather nice with this kit. The hangers are handed with a small turned bit that fits below the bracket whilst the spring rests on the top. In some kits, the turned bit has a bit of wire projecting whilst on others, you have to provide the wire (0.5 or 0.55mm). If the latter, le...

PS 'Fraid I have no RSU David..! You could still try the same technique using a bigger bit on your iron. After all, whether you use an RSU or soldering iron, you are just applying heat. Try tinning the nut, holding it in place and putting a big bit on top. Watch for the solder melting then remove t...

A thinned down nut could work quite well. You can solder the nut on with your RSU! See S4News No.207.

There's a lot to be said for Kodachrome, but no-one should presume it gives an accurate colour render. Without getting into the issues of scale effect, you need to add quite a lot more blue and green if you want to portray subjects like these 'realistically'. Interesting you say this. I remove blue...

Re: 1970s street scenes in colour - full of modelling detail

References like these are useful when it comes to painting. Compare the pictures with some painting and one finds the painting too vivid. On the whole, colours need muting. A tip given to me is not to use white to dilute paint but a flesh colour instead. Makes quite a difference.
